Smartphones have become an inseparable part of modern life, revolutionizing communication, work, and entertainment. However, excessive smartphone use (ESU) has been linked to various negative consequences, including addiction-like behaviors, impaired mental health, and diminished attention spans. Recent studies suggest that smartphone-related cues can trigger neural responses similar to those seen in substance addiction, reinforcing compulsive usage patterns. Understanding the effects of smartphone restriction on cue-related neural activity can provide valuable insights into developing interventions for individuals struggling with ESU.
The Role of Cue Reactivity in Smartphone Use
Cue reactivity (CR) refers to the brain’s response to stimuli associated with a habitual or addictive behavior. In the case of smartphone use, cues may include notification sounds, phone screens lighting up, or simply seeing a smartphone in one’s environment. These cues can activate reward-related brain regions, reinforcing the compulsive urge to check the device.
Research has shown that individuals with excessive smartphone use exhibit heightened neural responses to smartphone-related cues, similar to those observed in substance addiction. This heightened sensitivity may contribute to difficulty in controlling smartphone usage, leading to a cycle of compulsive checking and craving.
Investigating Neural Activity Changes Through Smartphone Restriction
To better understand how short-term smartphone restriction influences brain activity, researchers conducted a study using functional MRI (fMRI) to measure changes in cue-related neural responses over 72 hours of smartphone abstinence. The study involved 25 young adults who were regular smartphone users.

Study Design and Methods
- Participants were instructed to refrain from using their smartphones for 72 hours.
- A cue-reactivity task was designed, where participants were exposed to images of smartphones (both active and inactive) as well as neutral objects.
- Functional MRI scans were conducted before and after the restriction period to analyze changes in brain activity.
- Psychometric assessments were used to measure craving, self-control, and emotional responses associated with smartphone use.
Key Findings: How the Brain Adapts to Smartphone Restriction
1. Reduced Activation in the Reward System
One of the most striking findings was a significant reduction in activity in the nucleus accumbens and anterior cingulate cortex after 72 hours of smartphone restriction. These brain regions are heavily involved in reward processing and habit formation.
- The nucleus accumbens is associated with motivation and reinforcement learning. High activation in this area suggests strong craving and compulsive behavior.
- The anterior cingulate cortex plays a role in decision-making and impulse control. Reduced activity here indicates that participants may have experienced less compulsion to check their smartphones.
These findings suggest that even a short break from smartphone use can lead to neuroplasticity, allowing the brain to become less reactive to smartphone-related cues.
2. Alterations in Dopamine and Serotonin-Linked Activity
Further analysis using neurotransmitter probability maps revealed that activity changes in the reward system were closely linked to dopamine and serotonin receptor probabilities.
- Dopamine is a key neurotransmitter in reward-seeking behavior and addiction.
- Serotonin is involved in mood regulation and impulse control.
The findings suggest that smartphone restriction may influence neurochemical processes that drive compulsive behaviors. This could explain why some people feel withdrawal-like symptoms, including restlessness and anxiety, when they suddenly stop using their phones.
3. Increased Engagement of the Parietal Cortex
Another notable result was the increased activity in the parietal cortex, a region associated with attentional control and sensory processing.
- This suggests that participants became more aware of their environment and less preoccupied with smartphone-related distractions.
- Heightened parietal cortex activity was correlated with reduced craving scores, indicating improved cognitive control over impulsive smartphone use.
This supports the idea that limiting smartphone use can enhance focus and attentional regulation, reducing dependency on digital devices.
4. Reduced Compulsive Checking Behavior
Behavioral assessments showed that participants experienced a significant decrease in the urge to check their smartphones over time. This aligns with the observed neural changes in reward sensitivity and impulse control.
Participants also reported improvements in:
- Sleep quality: Reduced exposure to blue light and nighttime scrolling led to better sleep patterns.
- Social interactions: Without constant phone distractions, participants engaged more with people around them.
- Mental well-being: Several individuals noted feeling less anxious and more present in their daily activities.
Implications for Smartphone Addiction and Digital Detox Strategies
The findings of this study have significant implications for individuals struggling with excessive smartphone use. While a complete break from smartphones may not be feasible for everyone, implementing digital detox strategies can help manage usage and mitigate negative effects.
1. Scheduled Smartphone Breaks
- Taking regular breaks from smartphone use, even for a few hours a day, can help reset neural responses to digital cues.
- Setting specific times for checking messages rather than responding to every notification can reduce compulsive checking.
2. Mindful Technology Use
- Practicing conscious smartphone use by turning off unnecessary notifications and using grayscale mode can help decrease reliance on digital stimuli.
- Engaging in non-digital hobbies, such as reading, exercise, or meditation, can strengthen attention control and reduce smartphone dependency.
3. Sleep Hygiene and Nighttime Restrictions
- Avoiding smartphone use one hour before bed can improve sleep quality by preventing blue light exposure.
- Using do not disturb or airplane mode at night can minimize the temptation to check notifications.
4. Awareness Campaigns and Education
- Schools, workplaces, and mental health professionals can promote awareness of the impact of excessive smartphone use on brain function.
- Implementing digital wellness programs can encourage balanced technology use.

Conclusion: How Smartphone Restriction Reshapes the Brain
The study provides compelling evidence that even a short period of smartphone restriction can lead to measurable changes in brain activity. The observed reductions in reward-related neural responses, coupled with increased attentional control, suggest that limiting smartphone use can promote cognitive flexibility, impulse control, and overall mental well-being.
As smartphone addiction continues to be a growing concern, understanding the neurological basis of cue-reactivity and digital dependency is crucial. These findings highlight the importance of incorporating healthy technology habits to ensure that smartphones remain tools for convenience rather than sources of compulsive behavior.
By making small adjustments in smartphone usage, individuals can foster better focus, improved mental clarity, and greater overall life satisfaction. So, why not start with a 72-hour break and see how your brain adapts?
YOU WON’T BELIEVE HOW ‘GREASE’ STAR STOCKARD CHANNING LOOKS AT 80
After all these years, I don’t think there’s ever been a Rizzo as charming or relatable as Stockard Channing.
Channing was a talented actress, and her singing in *Grease* was amazing. But now, at 80 years old, she looks almost unrecognizable.
The first movie I ever saw Stockard Channing in was called *The Big Bus*, and I thought it was really funny. Back then, I never could have guessed that she would go on to have such an amazing career.
Today, Stockard Channing is best known for playing Betty Rizzo in *Grease*. *Grease* is a 1978 musical romantic comedy film based on a musical from 1971 with the same name. Many people, including me, think Channing was the best Rizzo out of everyone who has ever played the role.
A lot of people also know Channing from the TV show *The West Wing*, where she played First Lady Abbey Bartlet. Her acting was praised, especially her natural chemistry with Martin Sheen, who played President Josiah Bartlet.
“It just worked,” she said in an interview with *Entertainment Weekly* in 2020.
“We had this chemistry from the beginning. I don’t know what it was, but we had it and it didn’t go away. It was a happy accident.”
Starring as Betty Rizzo
Let’s take a closer look at the highlight of Stockard Channing’s career. To be honest, she hasn’t been in any major movies since Grease, even though she has kept acting in films and on Broadway.
Channing, who has been nominated for 13 Emmy Awards and seven Tony Awards, seems completely okay with being best known for playing the “bad girl” Betty Rizzo, one of the Pink Ladies in Grease.
But is that really all there is to her story?
Back in 1973, Channing had a small breakthrough when she starred in the TV movie The Girl Most Likely to…. It was a dark comedy about revenge.
“A lot of people talk about the G-word [Grease] and all of that, but back in the day, I had just as many people stop me on the street because of that one movie,” she said. “Because it’s about revenge, and people would sit in their living rooms and think, ‘Oh, I’m the only person watching this’ or ‘this person understands me.’ I’m not kidding. It was a million years ago, and then it was the highest-rated movie of the week. Revenge always works.”
Channing says she has only watched Grease twice.
“I used to be grumpy about Grease because I thought it was a kids’ movie or something. But now it’s kind of amazing. I’m very proud of it,” she told The Times in 2019.
The actress, who was born in Manhattan, was 33 years old when she played Rizzo, and playing a high school teenager wasn’t easy for her.
“I was much older than Rizzo in real life, but I couldn’t think about that. I had to imagine what I felt like when I was her age, or even younger. I thought about the complexity of being a teenager, with all the hormones, feelings, and issues around sexuality. Being older helped me show Rizzo’s sense of isolation,” Channing told Broadway World.
Channing, who got interested in acting at a young age, was very excited when she was offered the role of Rizzo. Her performance made her a big star in the late 1970s. She even won a People’s Choice Award for Favorite Motion Picture Supporting Actress. However, the actress from New York found it hard to get the same kind of success after Grease.
Channing was given two of her own sitcoms, Stockard Channing in Just Friends (1979) and The Stockard Channing Show (1980), but neither of them did well, and her career slowed down.
But Channing, with her Elizabeth Taylor-like looks and calm confidence, didn’t give up. She kept acting in many highly-praised movies and stage plays. Her most recent big-screen appearance was in the movie Angry Neighbors, which premiered in 2022.
Moving to London
In recent years, Stockard Channing has been involved in theater productions in London, where she now lives. She used to live in Maine with her partner of 25 years, but she moved to England in 2019.
“Living on my own here during the pandemic, I was sort of going through the same experience as everyone else in the country,” she told The Times.
Keeping a Low Profile
On a personal level, Stockard Channing has kept a low profile. The Grease star, who has always been known for being “reckless” and restless, has no children.
She has been married and divorced four times. Nowadays, she finds comfort in her dog, who has been her constant companion for many years.
Stockard Channing and Plastic Surgery
In recent years, Channing has also gotten attention for her changing appearance. It all started in 2017 when she was interviewed on Lorraine, a British breakfast TV show.
Here’s the article rewritten in simple language:

### Reactions to Channing’s Appearance
Channing was on the show to talk about her career and the roles she’s played, but many viewers were more focused on how different the *Grease* star looked. Many people were surprised by how much she had changed, leading to lots of talk on Twitter and articles in the tabloids.
“Oh my god, what has Rizzo done to herself?” one viewer wrote, while another said, “Shocked at how Stockard Channing looked on *Lorraine*. Why do they mess with plastic surgeons?”
In an article from the *Daily Mail*, a surgeon suggested that Channing might have used botox. However, others defended Channing. After all, we all get older, and it’s normal for an 80-year-old woman’s appearance to change over time.
To me, Channing still has that “Rizzo” personality – cool and confident! In an interview with *Out* magazine in 2011, she said she does “everything I f—ing can” to stay in shape.
“You get to a certain age, and you start playing a lot of mothers. Maybe if I had children, I’d feel differently, but I really hate being compared to these guys’ memories of their mothers, which, trust me, aren’t so great,” she laughed and added:
“Or maybe they watched a lot of *The Golden Girls*, you know? And while I’m thankful for *The Golden Girls*, they don’t spend time with women my age now, and I’d like to think the world has changed since then.”
